She did flash a stranger and later she was closing the bedroom door in my face

We were out for a drink one night and I bet my straight-laced girlfriend she wouldn't take her knickers off and flash a stranger. She went to the toilet and when she came back her panties were gone.

I was surprised enough by that but she wasn't done. She did flash a stranger and less than an hour later we were back at our place and she was closing the bedroom door in my face. I listened to them fuck for three hours.

When he had gone I was trying to snuggle with her and she looked me in the eyes and said: Our relationship changed tonight. You understand that right? It has changed for the better and it has changed forever.

She wasn't joking either and I've had the bedroom door closed in my face dozens of times since then.
